摘要：
We have studied the temperature dependences and kinetics of conductivity and the current-voltage characteristics of highly filled polymer-based nanocomposites containing CdS particles with an average size of about 50 Angstrom. The conductivity activation energy, electron density, and electron mobility were determined. The temperature coefficient of resistance of the nanocomposites at room temperature reaches 0.15 K-1. Polymer-based film nanocomposites with semiconductor particles are promising media for highly responsive temperature sensors, in particular, bolometers. (C) 2004 MAIK "Nauka/Interperiodica".
